Mono-White Myr deck (standard)

Hey guys just looking for some input on this myr deck list I've come up with.

The overall goal is to essentially overrun the opponent with myr and myr tokens while beefing them up with things like the galvanizer and tempered steel. While building up the tokens and regular myr the perilous myr ,sun titan, titan forge are defending.

Actually, if you're replacing land drops with chalices I'd just stick with the land. If you get stuck on one land + chalice (which at 16 land is likely) you're gonna be pulling your hair out. Best to leave it at 20 land and ignore the chalices. I didn't notice the resevoir and if you plan on knocking in that sun titan you're gonna want 20 lands.
